Abstract: The invention relates to a method, device and computer-program product for detection of undesired temporal variations (flicker) in a sequence of video frames. In one embodiment, frame-wise luminance means are compared with a reference level and the crossing frequency is compared with expected variation frequencies, such as frequencies associated with an illumination frequency through aliasing. The crossings count can be refined by introducing a latency zone around the reference level. In case of a positive detection of an undesired temporal variation, there is further provided a correction method, device and computer-program product using cumulated distribution functions. The visual detriment of flicker-induced saturation of pixels is alleviated either by brightening non-saturated pixels or by replacing the saturated pixels by randomly sampled values in accordance with a reference cumulated distribution function. The invention provides embodiments suitable for real-time processing of streamed video sequences.

Abstract: Methods and apparatuses use a pixel-adaptive interpolation algorithm to provide image upscaling. For each pixel location, the algorithm determines whether to use a high quality scaler algorithm (such as a polyphase filter, for example) or a directional interpolator to determine the pixel value. The determination of the appropriate interpolation algorithm is based on whether the pixel is determined to be an edge. If the pixel is determined to be an edge, the pixel-adaptive interpolation algorithm may use the directional interpolator to process the pixel; otherwise, the pixel is processed using a scaler algorithm.
